Time travel forward in time ? (after saving vel and trans arrays

Dear developers, in the picture below you see a way of reversing time
my question is, how to go forward in time ?

my second question; is there a way to play the transform array without removing the index
so that you can access it later ?

if you found a solution than i would be happy to receive a picture of the blueprint script
if you would be so kind.

Have u figured it out?

How about even backwards in time?

id save a transform and a timestamp rather than velocity, that way you dont need to save all on tick which would be hugely expensive. instead you can Interp between transforms
